ELECTRICAL CONTROL SYSTEM FOR AN ELECTRICALLY HEATED WINDOW IN MOTOR VEHICLE

摘要

An electrical control system for an electrically heated window in a motor vehicle has a voltage source including a generator, a voltage regulator for regulating a generator output voltage, a transformer switched between the generator and a heating window, the generator output voltage being increased before supplying to the heatable window, and a unit for measuring a temperature of the transformer and interrupting a communication between the transformer and the voltage source in the event of exceeding an adjustable limiting temperature.
